The Devil’s Slide inwards Utah , the United States of America , looks similar a giant playground slide tally alone for the Devil. The Slide consist of 2 parallel slabs of difficult , weather-resistant limestone stone nearly xx feet apart , some twoscore feet high together with 200 feet long. In betwixt these 2 difficult layers is a shaly limestone that is softer inwards comparing to the outer limestone layers , which makes it to a greater extent than susceptible to weathering together with erosion , thence forming the chute of the slide.
The Devil’s Slide is the tilted remnant of sediments deposited inwards a body of body of water that 1 time occupied Utah is the distant geologic past. “Approximately 170 to 180 1 M one thousand years agone , a shallow body of body of water originating from the due north spread southward together with eastward over areas of what are straightaway Montana , Wyoming , together with Utah. This body of body of water extended equally far eastward equally the present-day Colorado River together with southward into northern Arizona ,” explains the website of Utah’s Geological Survey.

“Over millions of years , massive amounts of sediment accumulated together with eventually formed layers of limestone together with sandstone. In northern Utah , these rocks are known equally the Twin Creek Formation together with are simply about 2700 feet thick. About 75 1 M one thousand years agone , folding together with faulting during a mountain- edifice episode tilted the Twin Creek stone layers to a near-vertical position. Subsequent erosion has exposed the near-vertical stone layers together with created Devils Slide.”
